Abstract:
A recording medium (100) for storing content that can be read and written by a host device stores a content key (a key that is used for encrypting content) (805a) encrypted in a first format, and a content key (805b) that is encrypted in a second format for content that is the same as the content related to the content key (805a) encrypted in the first format. The first format is, for example, a format used for distributed content, and the second format is a format used with local content.
